GSO eyepiece query

About 3 months ago I bought a GSO 8'' dob from Andrews which was well out of collimation for some reason. Andrews said it could have been dropped by the carrier which would not be surprising. I have it somewhere near now but notice when looking at a bright object a straight line cuts across the eyepiece. I dont see how it could be diffraction spikes caused by the vanes of the secondary mirror as the line turns when turning the eyepiece in the focuser so the question is it the eyepiece or I still do not have the scope set up properly? I am pretty new to this telescope stuff so need all the help I can!
